Aha. It appears I was correct in framing my knowledge as out-of-date. :-)

It looks like the technology *has* advanced, and that 10GE on MMF or SMF, single-channel, is what the current state of the art is, and at the $2k-3k unit price.

In which case, yes, not offering this (and not building cards to use cheaper and/or more flexible component, ie XENPAK), is likely going to be a huge mistake Cisco. Unless they bite the bullet and do whatever it takes to make xenpak-based 10G cards, on at least some flavour of card on any 10G platform.

(I don't really expect a xenpak-compatible version of soho routers to show up, although it *would* be nice as an option on most of their switch families.)

So, I sit corrected. ;-)

BTW, thanks for pointing this out; it's nice to see that things haven't completely stagnated in the last couple of years.

P.S. At that price level, I actually *do* expect another Swede will have, or already has, one or more of this class of box at home. In his WC, even. ;-)

P.P.S. He's not crazy. But he *should* have a t-shirt that says "I'm with STUPI". ;-)

Then why can I purchase 10km 10GE Xenpaks directly from the manufacturer for under $2000?

There is one. It's called CX4 and has a reach of 15 meters. Cisco sold it for $600 list price at first but it has now disappeared from the price list. I don't know why.
